Our Seamless Flat Roof Installation Process

Every successful flat roof installation starts with careful preparation and expert application. Our step-by-step GRP roofing process ensures your new roof will be completely leak-free and secure for decades.Structural Assessment: We begin with a thorough inspection of your existing roof deck, utilising our drone roof surveys where necessary to check for underlying water ingress or timber rot.Deck Preparation: We strip away the old, failing felt and install high-quality, interlocking OSB3 timber decking to create a strong, solid foundation.Applying the GRP System: Our directly employed roofers apply heavy-duty fibreglass matting, carefully rolling it out with specially formulated liquid resin to form a single, continuous layer with no vulnerable joints.Weather-Resistant Topcoat: Once cured, we apply a durable, UV-resistant topcoat in your chosen colour, providing the final seal against heavy rain and direct sunlight.

Why Choose Kevington for GRP Fibreglass Roofing in Swanley & Kent?

Why Choose a Fibreglass Flat Roof?

When comparing flat roof replacement options, glass reinforced plastic consistently ranks as one of the best investments you can make for your property. Here are the main benefits of choosing a fibreglass flat roof over traditional materials:Incredible Longevity: When installed correctly, a GRP roof has a lifespan exceeding 30 years, significantly outlasting traditional felt alternatives.Impact & Foot Traffic Resistant: The hardened fibreglass shell is tough enough to withstand heavy impacts, making it the perfect material for balconies, roof terraces, and accessible garage roofs.Completely Seamless: Because the resin cures into one continuous membrane, there are no welded seams or glued joints where water can easily penetrate and cause internal damp.Enhanced Safety: GRP is cold-applied. This means no naked flames or dangerous blowtorches are required during installation, providing total peace of mind for you and your family.Ready to upgrade your failing felt roof?

Common Questions About GRP Fibreglass Roofing

If you are considering a new flat roof installation in Tilbury, you likely have a few questions. Here are some of the most common queries we receive about our glass reinforced plastic systems:How long does a GRP flat roof last?When expertly installed using high-quality resins and topcoats, a fibreglass roof can easily exceed a lifespan of 30 years without requiring any significant maintenance.Is a fibreglass roof better than traditional felt?Yes. Traditional torch-on felt degrades over time, blistering in the summer sun and cracking in the winter frost. GRP is entirely seamless, eliminating the weak joints that typically cause felt roofs to fail.Can you walk on a fibreglass flat roof?Absolutely. GRP is highly impact-resistant. If you are planning a balcony or a roof terrace, we can even apply a non-slip finish to the topcoat for added safety and usability.

GRP Fibreglass FAQs

Frequently Asked Questions About GRP Flat Roofing

Got questions about upgrading or repairing your flat roof? Kevington Roofing and Building LTD provides expert answers on our durable, cold-applied liquid membrane systems for homes across Croydon & South London, Swanley, Sevenoaks, and Kent.

How much does a new GRP fibreglass roof cost in Swanley?

+

The cost of a fibreglass roof replacement in Kent depends on the size of the area and the condition of the underlying timbers. Generally, while the initial cost is slightly higher than felt, the fact that it lasts twice as long makes it the most cost-effective flat roof installation in the long run. We provide free, itemised quotes so you can see exactly where your money is going.

Can a GRP roof be installed in any weather?

+

Fibreglass needs dry conditions to cure correctly. While we can work throughout the year in Swanley, we carefully monitor the weather. We will never start a resin application if rain is forecast, as this would compromise the waterproof seal. Our team uses temporary coverings to keep your home dry at all times during the process.

Is GRP roofing noisy when it rains?

+

This is a common myth. When installed correctly with high-quality OSB3 decking and proper insulation, a GRP roof is no noisier than any other roofing material. In fact, many homeowners find it quieter than old thin felt roofs because of the solid timber base we install underneath the laminate.

How long will the installation take?

+

Most domestic flat roofs in Swanley, such as a standard garage or kitchen extension, can be completed in one to two days. We aim to work efficiently to minimise disruption to your daily routine, and we always make sure the site is safe and secure at the end of each day.
